ANNEX 31
EXCERPT FROM DOCUMENT IPC/WG/20/2 EXTRAIT DU DOCUMENT IPC/WG/20/2
Project C 443 (chemical) – Discussions were based on the latest rapporteur report (see Annex 26 to the project file). It was decided to amend the titles of subclasses C13B and C13K. Furthermore, the subgroups of subclass C13B were approved as well as the transfer notes from the deleted groups of subclasses C13C, C13D, C13F, C13G, C13H and C13J (see Technical Annexes 6 to 13 to this report). Rapporteur was invited to submit notes in subclass C13B explaining the use of the terms “sugar” and “sugar juices” in the said subclass. The French version of the project would be considered at the next session of the Working Group. Projet C 443 (chimie) – les délibérations ont eu lieu sur la base du dernier rapport du rapporteur (voir l’annexe 26 du dossier de projet). Il a été décidé de modifier les titres des sous-classes C13B et C13K. En outre, les sous-groupes de la sous-classe C13B ont été approuvés, de même que les notes de renvoi pour les groupes supprimés des sous-classes C13C, C13D, C13F, C13G, C13H et C13J (voir les annexes techniques 6 à 13 du présent rapport). Pour la sous-classe C13B, le rapporteur a été invité à présenter des notes expliquant l’emploi des termes “sucre” et “jus sucrés” dans ladite sous-classe. La version française du projet sera examinée à la session suivante du groupe de travail. ANNEX 6E C13B [ Project-Rapporteur : C443/DE

DE – Rapporteur Proposal — C443
The Rapporteur was asked submitting notes in subclass C13B explaning the use of the terms “sugar” and “sugar
juices”.
Please find a suggested wording –based on the definition proposed by EP in the related definition project– in the
following. For the sake of completeness R included an explanation of syrup as well.
Note
In C13B, the following terms or expressions are used with the meanings indicated:
– “Sugars” are any of various water-soluble compounds that vary widely in sweetness, include the mono-,
di- and oligosaccharides, and typically are optically active.
– “Sugar juices” are solutions of sugar, which are derived from different plants, e.g. beet, cane or maple.
– “Syrups” are highly concentrated sugar juices.
Furthermore there was agreement at WG20, that in C13B 10/00 the part of the title “, e.g. juices derived from
beet cane or maple” should be deleted from the scheme and be replaced by the second note above. Therefor it is
suggested to modify C13B 10/00 in the following way:
C13B
CL M 10/00 Production of sugar juices (tapping of tree-juices A01G 23/10; tapping-spouts, receptacles for juices A01G 23/14)

ANNEX 33
USPTO COMMENTS REVISION PROJECT: C443 Class: C13
Date: April 13, 2009
US comments are on the Rapporteur Proposal of annex 32 wherein Rapporteur explains sugar, sugar juice, and syrup. The explanations for the 3 terms are acceptable, but we wonder if they are a bit misleading. The title of C13B is “Production of sucrose; Apparatus specially adapted therefor.” Sucrose is considered a disaccharide and the explanation given by Rapporteur for “sugar” is much broader and could imply that production of all mono-, di- and oligosaccharides is to be classified in C13B. This is not the case, as I understand it.
IPC/C 443
ANNEX 34
Swedish Patent and Registration Office IPC Project C443, subclass C13 16 April 2009
Comment SE thanks the Rapporteur for the proposal in Annex 32. We agree with all but the first paragraph of the note, concerning the term “sugars”:
• “Sugars” are any of various water-soluble compounds that vary widely in sweetness, include the
mono-, di- and oligosaccharides, and typically are optically active.
Since the terms or expressions should be defined in the light of their use in C13B, the term sugar has too wide a definition. C13B is titled:
PRODUCTION OF SUCROSE; APPARATUS SPECIALLY ADAPTED THEREFOR (fermentation or enzyme-using processes for preparing compounds containing saccharide radicals C12P 19/00)
Thus, in the context of C13B sugar refers to sucrose. We propose the following phrasing:
• “Sugars” are used in its non-scientific term and refers to sucrose, also called “table sugar” or
saccharose. If a wider definition is desired, it could for instance be good to use the same definition in the note of C13B and C13K, we still believe the term “any of a various water-soluble compounds” to be far too wide. In that case we propose the following wording:
• “Sugars” are a class of edible, water-soluble crystalline carbohydrates, having a characteristic sweet
taste, including mono-, di- and oligosaccharides, e.g. sucrose, lactose, and fructose.

Comments 27 May 2009
Ref.: Annexes 32-34 We apologise for the late submission of this comment and hope it can still be taken into consideration before the Rapporteur Report. It seems strange to have two parallel discussions in project C443 and definition project D212 for the definition/note of "sugar" in C13B. The definition given in D212 seem to be acceptable - minus a minor modification, and the proposal of A. 32 reflects that. So we would like to support the proposal of DE in A. 32. Anne Glanddier.

United States Patent and Trademark Office IPC Working Group
Topic: WG111 - Introduction of New Residual Main Groups
Date: November 4, 2008
US comments on Rapporteur’s proposal of Annex 60 follow. US still prefers Rapporteur’s proposal for B67D rather than the proposal of JP in Annex 55. It would appear that Rapporteur’s proposal would not create the need for any intellectual reclassification, only automated changing of classification symbols on documents. US agrees that a revision project may be needed to sort out the C08H 5/02 (7/00) and 5/04 (9/00) versus C07G 1/00 issue in such a way as to minimize any reclassification of documents.

ANNEX 02
JAPAN PATENT OFFICE November 18, 2008
Project: WG111
JP Comment This is in response to IB Rapporteur proposal of October 14, 2008 (Annex 60). (1) B67D JP can accept the proposal made by IB. (2) C08H This is in response to Rapporteur’s invitation for comments with respect to the treatment of subclass C08H. JP can support the idea of creating a revision project for properly arranging C08H 7/00, 9/00 and 99/00. However, JP cannot agree with deleting C07G 1/00. Considering the title of subclass C07G being “COMPOUNDS OF UNKNOWN CONSTITUTION” and considering that “low molecular lignin” to be obtained by the degradation of lignin may possibly be an aggregation of various compounds which is exactly a “compound of unknown constitution”, it is believed that subject matters relating to “low molecular lignin” should be covered by C07G 1/00. On the other hand, the title of subclass C08H reading “DERIVATIVES OF NATURAL MACROMOLECULAR COMPOUNDS” makes it hard to believe that subject matters relating to “low molecular lignin” are covered by C08H. Since technology relating to “low molecular lignin” is not a subject matter of C08H either, the former loses proper place to be classified. JP believes that C07G 1/00 has a definite reason of existence in that subject matters relating to “low molecular lignin” are classified there. Therefore, JP objects to the deletion of C07G 1/00.

RENUMBERING OF PRE-REFORM RESIDUAL MAIN GROUPS 20. The Working Group further agreed to delete the residual main group C08H 5/00 and its subgroups, to transfer the deleted main group to new standardized residual main group and the deleted one-dot subgroups to new main groups, and to amend the title of subclass C08H (see Technical Annex 44 to this report). A new revision project C 455 was created, with the EPO as Rapporteur, for clarifying the overlap between the new main groups C08H 7/00 and 9/00 and the existing main group C07G 1/00. The International Bureau was invited to transfer the Annexes 61 and 62 of project file WG 111 to the new project.
RENUMÉROTATION DES GROUPES PRINCIPAUX RÉSIDUELS EXISTANT AVANT LA RÉFORME
20. Le groupe de travail est convenu en outre de supprimer le groupe principal résiduel C08H 5/00 et ses sous-groupes, de transférer le groupe principal supprimé vers le nouveau groupe principal résiduel normalisé et les sous-groupes à un point supprimés vers de nouveaux groupes principaux, et de modifier l’intitulé de la sous-classe C08H (voir l’annexe technique 44 du présent rapport). Un nouveau projet de révision C 455 a été créé, l’OEB étant désigné comme rapporteur, afin de déterminer les chevauchements entre les nouveaux groupes principaux C08H 7/00 et 9/00 et le groupe principal C07G 1/00 existant. Le Bureau international a été invité à transférer les annexes 61 et 62 du dossier de projet WG 111 au nouveau projet.

Rapporteur Proposal 10 February 2009
Background An overlap between group C08H7/00 (former group C08H5/02) and group C07G1/00 has
been identified. This proposal is aimed at clarifying the subject-matter
Comments - Lignin may be defined as an amorphous, polyphenolic material arising from enzymatic dehydrogenative polymerization of three phenylpropanoid monomers, namely coniferyl alcohol, sinapyl alcohol, and p-coumaryl alcohol. Because it is not possible to isolate lignin from wood without degradation, the true molecular weight of lignin in wood is not known, but is estimated to be 20,000. Strictly speaking, there is no low-molecular-weight lignin, but its derivatives are polyphenols as well, but of low-molecular-weight. - Concerning A. 4 of the project file, the informative references have not been deleted from the scheme, because no definition project on C07H exists yet. The wording of C07G13/00 has been modified as suggested by IB.
Scheme Proposal

ANNEX 06
USPTO COMMENTS REVISION PROJECT: C455 Class: C07G
Date: February 17, 2009
US comments are on the Rapporteur proposal of Annex 5. The newly proposed title for C07G 1/00, “Low-molecular weight phenolic compounds” does not appear to represent a compound of “unknown constitution” and seems to recite a compound which could be classified in the C07C 39/00 area, for example. It would also appear that this title has broadened the scope of what the old title encompassed. It now includes other low- molecular weight phenolic compounds which may not be lignin-related. Perhaps the title should be “Low-molecular weight derivatives of lignin.” Furthermore, what is the dividing line between low molecular weight and high-molecular weight? Concerning the addition of “of unknown constitution” to the title of 13/00, if this is to be done to this title, it would seem appropriate to add it to other titles of C07G groups, or not add it to any, since the title of C07G is “Compounds of unknown constitution.”

JAPAN PATENT OFFICE February 23, 2009
Project: C455 Subclass: C07G
JP Comment JP thanks EP Rapporteur for the Initial Rapporteur Report with scheme proposal as Annex 5 to the project file of C455. US immediately posted comments thereto as Annex 6 on February 17, 2009 in respect of the title of main groups C07G 1/00. As concerns the title of C07G 1/00, JP would support the US proposal for replacing “Low-molecular weight phenolic compounds” with “Low-molecular weight derivatives of lignin” because, if the former were adopted, other components than the derivatives of lignin would be covered by this main group, which would be an undue broadening of the scope.

ANNEX 08
Swedish Patent and Registration Office IPC Project C455, subclass C07G 03 Mars, 2009
Comment Sweden agrees with the US comment of Annex 06. The difference between low-molecular weight and high-molecular weight, used in the proposed titles of C07G 1/00 and C08H7/00 respectively, is unclear and the wording may render some confusion when classifying. When Japan argues for the continued existence of C07G 1/00 in Annex 02 they state that: “Considering the title of subclass C07G being “COMPOUNDS OF UNKNOWN CONSTITUTION” and considering that “low molecular lignin” to be obtained by the degradation of lignin may possibly be an aggregation of various compounds which is exactly a “compound of unknown constitution”, it is believed that subject matters relating to “low molecular lignin” should be covered by C07G 1/00” Perhaps a possible wording for the title of C07G 1/00 may be “Degradation products originating from lignin; Derivatives thereof”, or simply; “Lignin degradation products; Derivatives thereof”. Consequently, the wording of the title of C08H 7/09 may then be “Lignin”, followed by the proper reference to C07G 1/00.

ANNEX 09
JAPAN PATENT OFFICE March 6, 2009
Project: C455 Subclass: C07G
JP Comment JP reviewed SE comment of March 3, 2009, which suggested amending the title of C07G 1/00 as “Degradation products originating from lignin; Derivatives thereof”, and to amend the title of C08H 7/00 as “Lignin”. (C08H 7/09 was referred to in the SE comment, but should correctly be 7/00.) If such amendments were effected, however, those “high molecular derivatives from lignin”, that should be covered by C08H 7/00 from the beginning, might possibly be taken in C07G 1/00 instead. It would not be desirable to effect such amendments involving the danger of change of scope. [END]

Rapporteur Report 27 May 2009
Comments have been received from US (A. 6), JP (A. 7 and 9) and SE (A.8). Modification of 1/00
There is no agreement on the proposed title of 1/00.
US proposed to replace it with "Low-molecular weight derivatives of lignin" and is supported
by JP.
SE suggest “Degradation products originating from lignin; Derivatives thereof” or “Lignin
degradation products; Derivatives thereof" but is not supported by JP in their second
comment.
R. prefers the US proposal. Modification of 13/00 R. proposal is not supported by US. They are no other comments. Consequently, R. proposal is a s follows.
